    • fromGeoCoordinates

      @NonNull public static TileKey fromGeoCoordinates(@NonNull GeoCoordinates coordinates, int storageLevel, @NonNull TilingScheme tilingScheme)

      Creates a tile key containing specified coordinates at specified storage level and tiling scheme.

      For tiling schemes using Web Mercator projection, the latitude of input coordinates is clamped to [-85.05113, 85.05113] range.

      Parameters:
      coordinates -

      The coordinates for which to create the tile key.

      storageLevel -

      The storage level of the tile key, clamped to [0, 31].

      tilingScheme -

      The tiling scheme to use for the tile key.

      Returns:

      Tile key containing specified coordinates.
